    • A method and apparatus for repairing defect portions of a photomask. A complex material from which a light shading material can be deposited is applied over the photomask. A white (blank) defect region is irradiated with a continuous wave laser light beam projected in a slit-like light image to thereby convert the complex material into the shading material. After washing, a half-deposited portion formed in a peripheral portion of the light shading region is further deposited by a post-baking process. Those portions of the light shading film which depart from the desired mask pattern are removed together with black (solid) defect portion originally present in the photomask through irradiation with a pulse laser light beam. The pulse laser is constituted by a Dye-laser, while the continuous wave laser is constituted by an Ar-laser. A specific half-mirror which transmits therethrough Ar-laser light while reflecting Dye-laser light is displaceable provided. The white and the black defects are selectively centered on a same optical axis of an optical projection system including a slit and a condenser lens, whereby the white and the black defect portions are each removed through irradiation with the associated laser light projected thereto in a slit-like light image through the same optical projection system.
    • 一种用于修复光掩模的缺陷部分的方法和装置。 将光阴影材料沉积的复合材料施加在光掩模上。 用投影在狭缝状光图像中的连续波激光束照射白色(空白)缺陷区域,从而将复合材料转换成遮光材料。 洗涤后,通过后烘烤处理进一步沉积形成在遮光区域的周边部分中的半沉积部分。 通过照射脉冲激光,与原来存在于光掩模中的黑色(实心)缺陷部分一起除去遮光膜的偏离所需掩模图案的那些部分。 脉冲激光由染料激光器构成,而连续波激光由Ar激光器构成。 通过反射染料激光而透过其的Ar激光的特定半反射镜是可置换的。 白色和黑色缺陷选择性地集中在包括狭缝和聚光透镜的光学投影系统的相同光轴上,由此白色和黑色缺陷部分通过照射投射到狭缝中的相关激光而被去除 类似的光图像通过相同的光学投影系统。

    • An ion beam apparatus which comprises an enclosure defining a chamber of high vacuum. A crucible for producing vapor of a material, ionizing means, ion accelerating means, and a substrate to be deposited with the vaporized material to thereby form a film thereon are disposed within the chamber. An accelerating voltage is applied across the crucible and the accelerating means such that the crucible is of positive polarity while the accelerating means is of negative polarity. The material contained in the crucible is vaporized by heating. A pressure difference is maintained between the vapor pressure within the crucible and the vacuum chamber. The crucible is provided with a small hole for ejecting the vapor of the material into the vacuum chamber to thereby form atom clouds referred to as clusters under adiabatic expansion and supercooling, a part of the clusters being ionized through irradiation of electrons by the ionizing means and accelerated by the accelerating means so that the ionized and accelerated clusters deposit on the substrate to form a thin film thereon. The apparatus further comprises electrostatic optical system interposed between the cluster ionizing region and the substrate to be deposited with the ionized clusters, wherein the electrostatic optical system serves to focus the ionized clusters onto the element to form the thin film thereon through deposition of the ionized clusters.
    • 一种离子束装置,其包括限定高真空室的外壳。 用于产生材料的蒸气的坩埚,离子化装置,离子加速装置以及待蒸发的材料沉积以形成其上的膜的基板设置在室内。 在坩埚和加速装置之间施加加速电压,使得坩埚具有正极性,而加速装置是负极性的。 包含在坩埚中的材料通过加热而蒸发。 在坩埚内的蒸汽压力与真空室之间保持压力差。 该坩埚设置有用于将材料的蒸气喷射到真空室中的小孔,从而在绝热膨胀和过冷却下形成称为簇的原子云,通过电离装置照射电子而使部分簇离子化; 通过加速装置加速,使得电离和加速的团簇沉积在基底上以在其上形成薄膜。 该装置还包括插入群集电离区域和要沉积离子簇的基板之间的静电光学系统,其中静电光学系统用于将离子化的聚集体聚集到元件上以通过沉积离子簇而在其上形成薄膜 。
